Pro Channel FX Chain Module - Trim Noise!
Noticed when using FX chain, the trim sliders (at any position either + or -) for input and output gain introduce an nasty and incredible amount of jitter and distortion when I was using TH2. Double clicking and reducing to 0 stops the noise. Sounded like AC hum noise or a bad cable. 21.9.00 Platinum UGLY! (not that there are not many workarounds) Had me pulling my hair out for a while.
